Selling a Division Leaves Behind Costs It Used to Carry
A carve out separates part of a company and sells it. The overhead that unit was absorbing does not leave with it, and the leftover expense catches sellers repeatedly.
What a Carve Out Is
A carve out is the separation and sale of part of a company, usually a division or business line, to a buyer. It differs from a spin off, where the unit is distributed to existing shareholders as a separate listed company, and from a straightforward asset sale, because a carve out typically transfers an operating business with people, contracts and customers attached.
The complexity comes from the fact that the unit being sold was never designed to exist independently. It shared systems, staff, premises and contracts with the rest of the company, and those entanglements have to be identified and cut.
A division inside a company is not a company. Turning it into one is most of the work, and most of the cost.
Stranded Costs
The concept that determines whether a carve out creates or destroys value for the seller is stranded cost: expense that the divested unit was absorbing and that remains with the parent after the sale.
Suppose a company has 100 million of corporate overhead allocated across four divisions, and sells one of them. The buyer takes the division revenue and its direct costs. The parent still has its headquarters, its enterprise software licences, its finance organisation and its executive team. Very little of the 25 million the sold division was carrying disappears.
| Item | Leaves with the division |
|---|---|
| Division staff and direct costs | Yes |
| Dedicated facilities | Usually |
| Share of corporate finance and legal | No |
| Enterprise software licences | Mostly no |
| Executive team and headquarters | No |
The parent emerges smaller in revenue with a nearly unchanged overhead base, so margins deteriorate unless costs are removed deliberately. Sellers that model the transaction as simply removing the division profit and loss account are consistently surprised by this.
Carve Out Financial Statements
Buyers need historical financials for a business that never had any, because it was reported as a segment rather than as an entity. Carve out financial statements are constructed for this purpose, and they involve significant judgement.
Corporate costs must be allocated to the unit on some basis, shared assets must be attributed, and intercompany transactions must be restated as if they had occurred with third parties. The result is a set of accounts describing a business that did not exist in that form.
Buyers treat these statements carefully, because the allocated overhead in them is unlikely to match what the business will actually cost to run standalone. That difference is the reason diligence on a carve out focuses heavily on standalone cost estimates rather than on the historical numbers.
The Standalone Cost Gap
A division inside a large group benefits from scale it did not pay for at market rates: group purchasing, group insurance, an existing enterprise agreement with a software vendor, a treasury function borrowing at the parent credit rating.
Once separated, the business buys those things at its own scale and its own credit standing, and the cost is usually higher than the allocation it previously carried. The gap between allocated cost and true standalone cost is a central negotiating point, because it directly determines what the business is worth to a buyer who has to fund it.
A strategic buyer who can absorb the unit into its own existing infrastructure faces a smaller gap than a private equity buyer establishing the business independently, which is one reason the two bid differently for the same asset.
Transition Services
Because separation cannot be completed by closing, most carve outs include a transition services agreement, under which the seller continues to provide payroll, IT, accounting or other functions to the divested business for a defined period at an agreed price.
These arrangements are practical necessities and frequent sources of friction. The seller is providing services to a business it no longer owns, staffed by people who may be leaving, with no strategic interest in the outcome. The buyer depends on those services to operate. Terms, duration, exit rights and pricing matter more than their apparent administrative nature suggests, and a transition period that runs longer than planned is common.
Why Sellers Do It Anyway
Despite the complexity, carve outs are pursued for good reasons: raising capital, exiting a business that no longer fits, satisfying regulators after an acquisition, or removing a unit whose lower margins depress the multiple applied to the whole company.
That last motivation is real but conditional. It works only if the stranded costs are genuinely removed. Selling a lower margin division and retaining the overhead it supported produces a smaller company with worse margins, which is the opposite of the intent.
The Bottom Line
The value of a carve out to the seller depends less on the price achieved than on how much of the divested unit cost base actually leaves with it. Stranded costs are the recurring failure, and they have to be addressed through a deliberate cost reduction programme rather than assumed away. For the buyer, the equivalent discipline is to ignore the allocated overhead in the carve out statements and estimate what the business genuinely costs to run alone.
